Quizplus · Accepted Answer

Blood moves forward through veins primarily as a result of muscular compression from surrounding skeletal muscles, as well as through the action of valves that prevent the backward flow of blood. The pressure in the veins is in fact lower than in the arteries, but this pressure difference alone is not sufficient to move blood forward. Smooth muscle pumping is not a significant factor in moving blood through veins.
